FEATURES
Your Radio Shack Wireless Phone Jack System lets you add a
telephone jack anywhere you have an AC outlet, without drilling
holes, soldering, squeezing into cramped attic spaces, or fishing
a single wire through the wall.
The system also has these features:
Security Coding
— prevents someone using a similar system
from using your phone line.
Computer Modem Compatibility
— works with modems up to
14,400 bps.
Additional Extensions Available
— lets you add as many ex-
tension units (Radio Shack Cat. No. 43-161) as you desire.
Your system includes a base unit, an extension unit, and a 6-foot
modular telephone line cord.
Follow the simple instructions provided in this manual to install
your jack.
Notes:
• You can only use the Wireless Phone Jack System on one
phone line.
• During a power failure, only the telephone plugged into the
base works.
Warning: To reduce the risk of fire or shock
hazard, do not expose this product to rain or
moisture.

FCC INFORMATION
We have designed your Wireless Phone Jack System to conform
to federal regulations, and you can connect it to most telephone
lines. However, each device that you connect to the phone line
draws power from it. We refer to this power draw as the device’s
Ringer Equivalence Number, or
REN
(the REN is shown on the
base unit’s label).
If you are using more than one phone or other device on the line,
add up all the RENs. If the total is more than five, your phones
might not ring. In rural areas, a total REN of three might impair
ringer operation. If ringer operation is impaired, disconnect one of
the devices from the line.
Your Wireless Phone Jack System has a REN of 0.7dB; there-
fore, it should not affect your phones’ ability to ring. Also, the
phone you plug into the extension unit does not place any load on
the telephone line. However, the phone you plug into the base
unit might affect your phones’ ability to ring.
In the unlikely event that your Wireless Phone Jack System caus-
es problems on the phone line, the phone company can tempo-
rarily discontinue your service. If this happens, the phone
company attempts to notify you in advance. If advance notice is
not practical, the phone company notifies you as soon as possi-
ble and advises you of your right to file a complaint with the FCC.
Also, the phone company can make changes to its lines, equip-
ment, operations, or procedures that could affect the operation of
this system. The telephone company notifies you of these chang-
es in advance, so you can take the necessary steps to prevent in-
terruption of your telephone service.

FCC PART 68 AND CLASS B NOTICES
This Wireless Phone Jack System complies with Part 68 of
FCC
Rules
. You must, upon request, provide the FCC Registration
Number and the REN to your phone company. These numbers
are located on the base unit’s label.
Note:
You must not connect your Wireless Phone Jack System
to any of the following:
• coin-operated systems
• party-line systems
• most electronic key phone systems
This equipment complies with the limits for a Class B digital de-
vice as specified in Part 15 of
FCC
Rules
. These limits provide
reasonable protection against radio and TV interference in a resi-
dential area.
However, your equipment might cause TV or radio interference
even when it is operating properly. To eliminate interference, you
can try one or more of the following corrective measures:
• Reorient or relocate the TV or radio
• Increase the distance between the equipment and the radio
or TV
• Use outlets on different electrical circuits for the equipment
and the radio or TV
Consult your local Radio Shack store if the problem still exists.

LIGHTNING
Your Wireless Phone Jack System has built-in protection circuits
to reduce the risk of damage from surges in telephone line and
power line current. These protection circuits meet or exceed the
FCC requirements. However, lightning striking the telephone or
power lines can damage your telephone.
Lightning damage is not common. Nevertheless, if you live in an
area that has severe electrical storms, we suggest that you un-
plug your phone during storms to reduce the possibility of dam-
age.

USING THE SYSTEM
It is very important that you follow all instructions in the order giv-
en. If you have a problem, unplug both units from the AC outlets,
unplug the phone(s) from the units, and start over (or see “Trou-
bleshooting” on Page 13).
INSTALLATION
1. Plug the base unit into a standard AC outlet that is near a
modular telephone jack. (The base unit has two modular
jacks on one side.)
Caution:
Do not plug the base or extension unit into a power
strip or surge protector/AC line filter.
2. Plug one end of the supplied modular telephone cord into the
LINE
jack on the side of the base. Then plug the other end of
the cord into a modular telephone jack.
Note:
Be sure to plug in the base unit before you plug in the
extension unit.
3. If desired, connect a telephone to the base unit by plugging
its modular cord into the
PHONE
jack on the side of the base.

4. Plug the extension unit into any AC outlet. (The extension
unit has only one modular jack.) Then plug a telephone’s
modular cord into the jack on the side of the extension unit.
Notes:
• Longer modular telephone cords are available from your
local Radio Shack store.
• If your phone line jack is not a modular jack, you can update
the wiring yourself, using jacks and adapters available at
your local Radio Shack store. Or, you can let the phone com-
pany update the wiring for you. The USOC number of the
jack to be installed is RJ11C.

SETTING THE SECURITY CODE
This system has preset security codes which prevent interference
and background noise caused by similar systems. If you
encounter interference, follow these steps to set your security
codes.
Note:
You should only need to set the security code if you get in-
terference from another system.
1. With both the base and extension unit(s) installed and any
connected telephones on hook, press the coding button on
the side of the base unit with a pencil. The green indicator on
the base turns on.
2. Press the coding button on the extension unit within 5 min-
utes.
• If the code is successfully set, the extension unit’s indica-
tor blinks once.
• If the code is not set, the indicator continues to flash. Try
pressing the coding button on the extension unit several
times until the indicator stops flashing. if you cannot make
the indicator stop flashing, start over again at Step 1.

3. Wait for the base unit’s indicator to turn off. Then lift the
extension telephone’s handset and confirm that you hear a
dial tone and that there is no interference or background
noise. If there is a problem, repeat these steps.
If you cannot get a dial tone, unplug the cords from both phone
jacks and reset the units (see “Resetting the System” on
Page 12).
ADDING MORE EXTENSION UNITS
You can add as many extension units (Cat No. 43-161) to the
system as you want. Simply install the extension by following
Steps 4 and 5 in “Installation.” Then follow the steps in “Setting
the Security Code” on Page 10 to set each extension’s code.
You can use only one extension at a time, even if you install more
than one. If you lift the receiver on a phone connected to an ex-
tension unit while another extension unit is being used, you hear
a busy signal.
USING THE SYSTEM WITH A COMPUTER
MODEM
Simply plug your computer modem’s telephone cord into an ex-
tension unit’s modular jack. The system supports speeds up to
14,400 bps.
Note:
If there is static on the system, you might need to set your
modem to a slower speed for effective communications.

TROUBLESHOOTING
We do not expect you to have any problems with your system,
but if you do, the following suggestions might help. If you still
have problems, disconnect the base and all extensions and take
them to your local Radio Shack store for assistance.
Problem Suggestion
Static interference. Move the base or extension unit(s).
Fluorescent lights, light dimmers,
computer surge protectors, and
home automation controllers can
cause interference.
Cannot set the secu-
rity code.
Move the base or extension unit(s).
Try the security code procedure sev-
eral times. If that does not work,
reset the system then try again.
Cannot dial out. Decrease the distance between the
base and the extension unit(s).
Be sure the outlet has power. During
a power failure, only phones con-
nected to the base or directly to the
phone jacks operate.
Phone does not ring. Decrease the distance between the
base and the extension unit(s).
No dial tone or a high
pitched beep from the
handset.
Reset the system.

CARE AND MAINTENANCE
Your Radio Shack Wireless Phone Jack System is an example of
superior design and craftsmanship. The following suggestions
will help you care for your system so you can enjoy it for years.
• Keep the system dry. If it gets wet, wipe it dry immediately.
Liquids can contain minerals that corrode electronic circuits.
• Use and store the system only in normal temperature envi-
ronments. Temperature extremes can shorten the life of
electronic devices, and distort or melt plastic parts.
• Handle the system gently and carefully. Dropping it can dam-
age circuit boards and cases and can cause the system to
work improperly.
• Keep the system away from dust and dirt, which can cause
premature wear of parts.
• Wipe the system with a damp cloth occasionally to keep it
looking new. Do not use harsh chemicals, cleaning solvents,
or strong detergents to clean your system.
Modifying or tampering with the system’s internal components
can cause a malfunction, invalidate its warranty, and void your
FCC authorization to operate it. If your system is not performing
as it should, take it to your local Radio Shack store for assis-
tance. If the trouble is affecting the telephone lines, the phone
company can ask you to disconnect your Wireless Phone Jack
System until you have resolved the problem.
